ADJUSTABLE was.

To all whom it may concern Be it known that I, HERBERTC. TAYLOR, a

citizen of the United States, and a resident of Greensburg, county of Decatur, and State of Indiana, have invented a certain'useful Adjustable Oven; and I do hereby declare that the following is a full, clear, and exact description thereof,"reference being had to I the accompanyingdrawings. p

The object of this nventlon 1s to combine an oven with a plurality of sources of heat,v

such as burners, stove holes or "any other means for heating and an ad ust able partition or partitions the oven'so as to adapt "the oven for use with only one burner or source of heat or with two ormore burners 1 or sources'of heat.

In the drawings herein aportable oven; is shown in connectlon'w th a gas stove hav- 1 ing burners, but the inventlon' 1s .not limited to the portable oven nor to the gas stove.

With this arrangement the oven g'charnber can be readily adjustedto suit the need at any particulartime and thereby save the PP fuel and also laiiord' other advan- If one burner be used, thered'uction heat or and the oven chamber beilimited to only one of said burners, not only willithere be a saving of heat and i:'uel but, if desired, ,the other burners can at the s'amef' 131mg be used for other ur osessuch'as or ing or I I I k p p y half the depth of the oven. As heretofore heating water.

The natureof the invention be understood from the accompanying drawings and "the following description and claims: l In the drawings, Figure 1 is a perspec-- tive of my oven placed upon a hot plate. Fig. 2

p is a vertical mid-section longitudinally of the oven. Fig. 3 is a vertical trans- 1 "Verse section on the line33 of Fig. 2.

Fig. 4 is a perspective of the flame spreader.

In detail there is shown'in' the drawings.

an oven 10 suitable for agas or oil stove and i receiving heat fromtheburnersof a stove '11." Said oven is formedof sheet metal after.

the heat from the burners: toward the front and rear walls. Insulatingchainbers 15 and pe fiq l t Patented sepia-1,1914} f y 'Applicationfiledll'anii'ary22,1312.fSeria1No.672,615.

16, adjacent to the backland top, respec tively, ofthe oven,"p'rovide a deadair' or insulating space to reduce the radiation of heat from the oven;* Said, chambers15 and 16 are divided into three chambers by JUI- shaped' partitions 1l5'see Fig. 2, forthe pufpose hereafterdescribed. I

There'is an adjustable insulating or dead air chamberjl'l normally lying adj acenteach end wall 18,]which may: be moved inwardly to reduce the distance therebetween, thereby reducing the active radiating surface of the oven. Said insulating chambers 17 are boi like in form andhave a-sh'eet '19 trsome;

"poor heat conducting material, such'as asbestos, within the same and on the side ad jacent the interior of the oven. Said "partitio'n chambers I'Z'are supported by the bottom flange40 o'fthe oven and each partition has throughfit a triangular opening- 20 through which the heat deflector 14 extends and whereby said orted. v

The heat deflector 14, is formed of sheet metal and is substantially an isosceles trianglein cross section and is supported in the openings in the" chambers 17 with the'base of the triangle upon the upper side and the vertex adjacent the burner. In length said heat deflector is equal tothe distancebetween the "outer end walls 18*and the width of the base is substantially morethariQone mentioned it is substantially midway be tween the front:doorand rear'wall ofthey oven and 1 leaves a passage upon either side 4 oven andthe tongue 22of theg 'netalfthus "formed is bent downward to close the pasv sage through the deflector: j, "Midway be-- tween its ends there are two'tr'an'sve'r'se slits 23jin'the upper face 26 through which thel e11'ds24of a" U shaped piece of metalf'extend and divide" the interior of the'deflectorinto two chambers withwa dead airspace between them. The portion 25 between the rojections 2 L lies fairly flat on the upper ace -26 of the deflector. Upon each side of said flat portion 25a rectangular opening 2735 out in the face 26 and the inclined. lower sides of said deflector 14 have perforations 28 to -racks; are slid. into place on the ribs 21' andthe reduced portion of the oven may be placed over a single burner and heatedby the same. The major portion of the heated gases arising will be deflectedto the front and rear as usual, but a part will enter the interior of the deflector through the perforations 28 and pass out throughthe openings 27 and 29 adjacent the end walls and keep them heated. The. short oven racks 30 are of such a length; that the adjustable chamber 17 will be opposite one set of the partitions 1151 and heatcannotescape behind or over the chamber 17 and the U- shaped partitionin the heat deflector lj l will prevent an escape of heat from the heated to the unheated vent any passage of heat to the exterior end wall 18. Either of the members 1 7 may be adjusted and there are two U-shaped strips 3-2 of sheet metal secured to the inside face of the door 12, one ofwhich will engage the w. front edge of the insulating member '17; and

' seal the frontedge against a loss of heat deending upon which of said members has een moved inward. The usual perforations 33 and 34 are'provided in the members. 1 7 andtheend walls 18, respectively,

to. promote afcirculation of the heat within the oven. There is a ring 35 in eachfof'said members 17 to assist in moving and adjusting the" same.

By this invention the top of thestove may be used with greater efficiency, for withv a stove with, say three burners, the ordinary oven of similar size when set on the .top of the stove occupies space so that it is placedover two of the burners, but with this invention it willbe possible to place the oven chamber toward one end or the other so thatone burner is located directly under the part of the oven which it is desired to heat and have theyother burners left. for

otheruses ;.whereas in all the ordinary. ovens of the size which occupies enough space to set over two burners of theordinary threeburner; stove, the space ofv two of the burn ers is covered. in heating the oven for general cooking.. i

. I claim as my invention:

2. The combination of an oven adapted to be heated by a plurality of heating means and a member loosely disposed within the oven and normally lying adjacent one wall thereof whichmay be adjusted to any pos1- tion between the ends thereof for reducing the size of the. heating chamber and the number ofmeans necessary for heating the same.

3. The combination of an oven having an open bottom, aplurality of separate means for heating the'same, and a non-conducting member loosely disposed in each end of the ovenwhich may be adjusted to any positionbetween the ends thereof, said members being normally positioned adjacent the outer end walls, thereof.

l. The combination ofan oven having an open-bottom, a plurality of separate means for-heating the same,and a non-conducting chamber looselydis'posed within the oven andnormally forming a part of one wall thereof which may be adjusted tion between the ends thereof.
